Application filed ma 23, 1922. Serial N0. 562,950;

To aZZ whom it may concern Be it known that FRANK l. CLARK, a citizen of the United States, residing at Balti: more, in the State of Maryland, has invented certain new and useful Improvements in Inhalers, of which the following is a speci- This invention relates to improvements in inhalers and is particularly an im rovement on the inhaler shown in Letters atent of the United States granted to me May 26th,

1908 and numbered 888,869.

The invention is illustrated in the accompanying drawing, wherein,

Fig. 1. shows one of the improved inhalers attached to the nostrils of a user.

Fig. 2. illustrates the elevation. i

Fig. 3. shows the same in side View.

Fig. 4. illustrates a vertical sectional detail through the inhaler,the section being taken through one of the nozzles.

Fig. 5. shows the several parts of the inhaler in perspective, and

Fig. 6. illustrates a sectional detail through a portion of the engaged tubular sections with the loop of the wire clamping frame projecting into the retaining opening in one of them.

Referring to the drawing the numeral 8 designates one of the tubular or cylindrical sections and 9 the other of said sections.

The section 8 comprises a tubular shell having one end 10 closed and its other end 11 open, said shell having about one-half of its external diameter at 12 smaller than the other half thereof so as to form a central circumferential or annular shoulder 13 at a point about midway between its closed and open ends.

The section 8 also hasprojecting from its larger diameter a slightly curved and somewhat tapering nozzle 14 which latter has a passage 19 extending therethrough from its outer end and which opens on the interior of the section.

About midway'between its two ends this section 8 also has a central opening 15 with notches 16 at its opposite sides said opening and its notches extending through the shoulder 13 and projecting partly into the reduced portion and partly into the enlarged portion of said section.

At each of the opposite sides of the central opening said shell also has two air-inlets or perforations 17 ,one of which is clearly inhaler in front shown in Fig. 5 and the other in Fig.2 of

the drawing.

- The other section f the inhaler is of an internal diameter that will enableit to telescopically receive the reduced end of the section 8 and is of an external diameter that is" equal to the external diameter of thelarger endoof said section 8 so that when the two sections are fitted together their external diameters will be flush. J

This section 9 also has a slightly curved and tapering nozzle 18 with a passage/l9 extending therethrough from its outer end and opening into the interior thereof as."

clearly shown at the left side of Fig. 5. I,

By again referring to Fig. 5 it will be seen that this section 9 also has asegmental notch-out portion 20, alongits inner edge at. a point substantially diametrically thenozzle 18, which notch, when the two. sections are telescopically engaged, will bridge or extend from the far side of one perforation 17 past the central openingl5 andto the far side of the other perforation 17 so that neitherof those perforations or the central opening will be closed by the wall of the section 9 when. the latter. receives the reduced end of the section 8. 2'

The outer end 21 of the section 9 is closed and imperforate like the end 10 of said section 8.

I also employ in my improved inhaler a detachable wire clamping-frame which comprises an intermediate cross-stretch 22 and two side stretches 23 each of which latter has an outwardly or forwardly-curved end 2 1. Each of these side stretches and its curved end is preferably covered with a tubular material 25, such as rubber because these ends are to engage the opposite sides of the nose of the wearer to hold the inhaler in place.

The intermediate cross-stretch 22 of the wire frame is provided with a loop or bend 26 which latter is designed to be entered in the central opening 15 and then turned so that the two side stretches of the loop will seat in the notches 16 at opposite sides of the opening and thus hold the frame in place.

The length of the cross-stretch 22 is such that when the two sections 8 and 9 are engaged, the side stretches 23 will lie close against the two closed ends 10 and 21, and prevent the two sections from separating.

By reference to Fig. 2, of the drawing it p it will be noted that the entrance for air into the interior of the sections is through the central opening 15 and the two perforations 17 whereas the nozzle-passages 19, communicate with the interior of the sections near each end thereof and at opposite sides of said opening and perforation;

. The medicament 1s sprinkled or otherwise.

arranged in the interior of the'sections be tween the two nozzle-passages 19 so that air drawn through the centrally-arranged openings must pass laterally through the medicament before it can be drawn through the nozzle-passages 19 into the nostrils.

The device is applied as shown in Fig. 1 ofthe drawing wherein the nozzles i l- .8 are inserted in the nostrils and the curved ends 24 of the frame engage the sides of the nose to hold the inhaler in place.

By making the parts separable and dctachable as I have done, they may more readily be cleaned and sterilized.

Having described my invention, I claim,-

1. An inhaler comprising. two telescoping sections each section having a nozzle opening into the interior of the section, said sections having circumferential openings located in a plane between the two nozzles and a wire clamping frame detachably connected to the sections at one of said openings said frame being shaped to engage the nose of a person to hold the inhaler in place. 2. An inhaler comprising two cylindrical sections one having a reduced portion: to

enter the other and each being provided with therein to enter said opening and engage in said side notches said frame also having side portions to project upwardly at the ends of the two sections to engage the nose of a person. I

1. An inhaler comprising two cylindrical sections each having a nozzle and one section being provided with a reduced portion to telescopically enter the other section, the other section being provided with a circumferential notch and both sections being closed atthe ends, the section'with the reduced portion having a central openingwith an opening at each side thereof which open-- ings register with the circumferential notch in the other sections when the two sections are engaged, and a wire frame detachably engaging the central opening of the one section and having side portions to engage the nose of a person to hold the inhaler in place.

In testimony whereof I affix my signature. FRANK I. CLARK.
